We worked on a sample of 254 vegetable farmers. The analysis shows that the biophysical characteristics of riparian areas are influenced by environmental degradation. The means of transporting water from the source to the garden are favorable thanks to surface water, 60% concerning the well and drilling, this is visible in 35% of the farmers and only 6% are reserved for rainwater. 58% of the farmers are ready to adopt the irrigation by solar system and among this 23.4% already use the solar irrigation system and think that these technologies have a positive impact on the management of the climate change In terms of equipment, 72.4% of the farmers use motorized pumps (gasoline diesel) to transport water from the source to the plot. Thus, only 26.4% have adopted the system of pumps powered by solar energy and 1.2% are satisfied with the winter campaign. In the end, we found that the intensity of farm mechanization increases with farm size and decreases with the increase in family labor. We have formulated economic policy implications tending to make solar equipment more accessible for better performance by small farmers.
